The components look about five years older than the frame. There only appear to be 6 cogs which would put the Dura-Ace circa 1985-1986. The frame has dual bottle bosses and a front derailleur tab. Given the components that would notamlly make this a TSD era, CLX model but it's missing the chromed stays and the dropouts are too short.

The decal below the seat and top tube juncture looks silver. Normally this would be the tubing decal and would indicate Cromor. However, that's not a Cromor decal on the fork. I can't make it out. The OP needs to determine the tubest before I'm willing to offer further assement.
